Hello, I have a server pfsense in bridge mode to function as transparent FW, the problem is that once I connect the pfsense between my router core and my core switch catalyst a few seconds begin to appear several messages like these: em2: watchdog timeout - resetting em2: watchdog timeout - resetting em2: watchdog timeout - resetting em2: watchdog timeout - resetting And the connection falls back repeatedly and indefinitely. Searching on google did some tweaks: hw.em.rxd = "4096" hw.em.txd = "4096" hw.em.tx_in...

Hello All, I seem to have run into a bug with the new --bridgeslaves=<INTERFACE> option. It would seem that if I tell the bridge device to use a virtual interface (like bond0) rather than a physical interface (em1/em2) that kickstart completely barfs on it. I have provided my network section below which works fine as long as i don't enable all the bridge content. When the installation starts off the creation of bond0 and all VLANs on bond0 go without issue. Jumping into TTY2 I can type 'ip a' and...

...unning CentOS 7.5. This server has one 4 port NIC and one 2 port NIC and a Dell IDRAC port. The first port of the 4 port NIC, em1, is used for Management traffic. The first port of the 2 port NIC, is used for the second port in the NIC bond, device p6p2. The second port on the 4 port NIC, device em2 is the first, port on the NIC bond. These interfaces are using Static IPs. Here is my /etc/sysconfig/network-scripts/ifcfg-em1 file.

I suspect I'm not getting route announcements. I think I have all the IPv6 variables in ifcfg-em2 set right. But I do notice that the accept_ra file in proc for that interface has value 1, not 2. Changing it to 2 doesn't change anything, though. No route appears. While I wait for an answer to my trouble ticket, is there some way to verify that I'm not receiving any RA packets? Is th...

With biosdevname, you get devices like 'em1, em2, p6p1', which aren't as friendly as 'eth0' but also keep names sane and avoid the hair-tearing issues you're experiencing currently. You don't appear to be adding anything via your append line that would disable biosdevname, so I must assume you're using a much older 6 b...
